Together with Greg Wooledge's observation that "make"'s macro definition
does not interpret `...` as output of shell commands we already have
two reasons why that part of the Makefile should not work.

The riddle grows why it appears to work on Gentoo.

----------------------------------------------------------------------

  info make
shows a "MAKE(P) POSIX Programmer's Manual" which explains that what i
perceive as variables are indeed macros. No mentioning is to see of any
shell-like properties.

The web has workarounds with GNU make:
  https://stackoverflow.com/questions/10024279/how-to-use-shell-commands-in-makefile
This is confirmed by
  https://www.gnu.org/software/make/manual/html_node/Shell-Function.html

Alternatively i would try to hand over the "-I..." argument by an
environment variable.

But i guess the autotools way is to insert the desired arguments at
latest when ./configure creates Makefile from Makefile.in.
(Now we could need hearsay about how this is to be done ...)


Have a nice day :)
